This month's Comic Shop News features SUPERMAN #5 (Jan 2012)
on its cover. The two-page article discuss why George Perez is leaving
the title and Dan Jurgens and Keith Giffen will be taking over with
issue #7.

Quote from George Perez: "I miss drawing. I can't see
myself staying on as a writer, because I want to draw. That's why I
really wasn't enjoying the writing as much as I would have hoped. I was
asked to do Superman based on stuff that I had done before;
however, since it was a total relaunch, I didn't recognize the character
and feel as close to him as I had hoped I would, because it didn't seem
like my Superman."

The free newspaper can be found free at most decent comic book shop, so check around if your store doesn't carry this.
